In prokaryotic cells, it takes place in the cytoplasm with the transcription of many ribosome gene operons. In eukaryotes, it takes place both in the cytoplasm and in the nucleolus. It involves the coordinated function of over 200 proteins in the synthesis and processing of the three prokaryotic or four eukaryotic rRNAs, as well as assembly of those rRNAs with the ribosomal proteins. Most of the ribosomal proteins fall into various energy-consuming enzyme families including ATP-dependent RNA helicases, AAA-ATPases, GTPases, and kinases. Ribosome biogenesis is a very tightly regulated process, and it is closely linked to other cellular activities like growth and division. Some have speculated that in the origin of life ribosome biogenesis predates cells and genes and cells evolved to enhance the reproductive capacity of ribosomes. ==Ribosomes== Ribosomes are the macromolecular machines that are responsible for mRNA translation into proteins. The eukaryotic ribosome, also called the 80S ribosome, is made up of two subunits – the large 60S subunit (which contains the 25S (in plants) or 28S (in mammals), 5.8S, and 5S rRNA) and a small 40S subunit (which contains the 18S rRNA and 33 R proteins) as well as 46 ribosomal proteins. The ribosomal proteins are encoded by ribosomal genes or rDNA. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Ribosome biogenesis」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
